To all whom z't may cc cerm B( it known that we, GEORG HAYN, residing at Essen-on-the-Ruhr, Germany, and NORBERT KOCH, residing at Essen-Bellinghausen, Germany, both subjectsof the Emperor of Germany, have invented a certain new and useful Improvement in Automobiles with Pivot-Guns, of which the following )s a specification.

T his invention vrelates to automobiles with pivot guns and consists primarily in a special arrangement of the platform for the gun. In the drawing, Figure' 1 is a side elevation, partly in section, of one embodiment of the subject matter of the invention; Fig. 2 is a corresponding plan view; and Fig. 3 is a detail. v

The pivot support A (Fig. l) of the gun, is rigidly connected with the frame B of the automobile. In the pivot support, the fork shaped upper carriage D is rotatably mounted through means of a ball bearing al and a vertical pivot d1. There is further mounted rotatably upon the frame B, a platform E for the gunner, through the medium of a second ball bearing e1 concentric to the axis of the gun pivot. The platform carries an armor F, in the rear side of which is provided an opening f1, which affords access to the platlorm E. To facilitate entrance upon the platform, the latter has a recess e2 (Fig. 2). Upon the upper carriage D is provided' an attachment d2 which serves to receive a coupling bolt cl3. This bolt engages, with some. play, in a recess of the platform E. Upon the platform, at either side of the gun barrel C, ammunition holders G are provided. Two additional ammunition holders H rest upon the automobile frame B.

In consequence of the described arrangement of the platform E and its connection 'with the upper carriage AD, the plat-Vorm will swingtogether with the gun. Nevertheless, the pivot of the gun barrel is Vrelieved of the weight of the platform,v of the serving crew, of the armor, of the ammunition holder G, etc., so that a'steady' support of the gun is attained.

A securing arrangement is provided for the gun barrel which serves to relieve the aiming mechanism, during the travel of the automobile, by fixing relatively7 to the latter, the gun system (the gun barrel C, its slide track carrier, etc.) swingingabout-the axis 4form to turn together,

of the horizontal trunnion d* and the axis of the pivottrunnion d1. This securingarrangement consists of a clamp `K jointed to a bearing L, mounted on a vertical wall J of the automobile and provided with a recess el shaped to conform to the muzzle end of the gun barrel. Rigidly connected with the -clamp K is a lever 7a2, which is jointed to a rod M. The rod M is swingingly mounted through means of an intermediatelever m1, upon a bearing m2 and carries on its end a fork m3. This fork is adapted to embrace an eye N, arranged on lthe platform E and is secured to this eye through the medium for the gun barrel is thus so combined withA a securing arrangement for the platform that when the gun is secured, the platform is simultaneously secured also. When the two securing arrangements are out of operation, they assume the position shown in Fig. 3, in which they will be secured by a means not shown on the drawing, for example, a bolt or an abutment.

IVe claim:

1. In anv automobile having a pivot gun, an automobile frame, a rotaryA bearing by which the gun is mounted on the frame, and a platform having a rotary bearing on said frame independent of the gun bearing, and securing means comprising a cap and a link, both journaled in the automobile frame, a connecting rod hinged to said cap and said link, an extension member on said rod, a socket on said platform and a key in the socket for engaging said extension member; said cap constructed to fit closely over the gun muzzle, whereby the gun will be held securely in both horizontal and vertical di- Q rection, and said platform in horizontal direction when said key engages said eXtension member.

2. In an automobile having a pivot gun, an automobile frame, a rotary bearing by which the gun is mounted on the frame and a platform rotatable independently of the gun and mounted on said frame, coupling means for connecting the gun and the platand securing means adapted to engage the .platform and a part of the gun partakng of its elevation nd The foregoing specification signed at Bart'raining movemensf,A s ad securing means bemen, Germany, thls 28th day of September, 10 f mounted on safame and connected to 1911.
